Specification of Letters Patent.

Patented July 23, 1912.

Application filed August 30, 1911. Serial No. 646,805.

To all whom it may concern:

Be it known that I, FRANK BUMER, a citizen of the United States of America, residing at Monessen, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Pens, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to pens, and the objects of my invention are to providefirst, a pen with a small reservoir in which a small quantity of ink can be stored whereby the pen-point can be used for a greater period of time than an ordinary pen-point, withoutreceiving a new supply of ink; second, a pen point having a guard that prevents the dropping of ink, when the pen point is being placed in use, thereby preventing paper and valuable documents from being soiled and ruined by blots of ink; third, a pen point that can be used in connection with various types of holders and manufactured at a comparatively small cost.

lVith the above and such other objects in view, as may hereinafter appear, the invention resides in a novel construct-ion to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein like numerals denote corresponding parts throughout the several views, in which Figure 1 is a perspective view of a pen in accordance with this invention; Fig. 2 is an enlarged plan of the pen point; Fig. 3 is a longitudinal sectional view of the same; and Fig. 4 is an enlarged cross sectional view taken on the line IVIV of Fig. 3.

A pen point in accordance with this in vention is constructed somewhat similar to the ordinary well-known Falcon pens. The pen point having a curved body 1, with the rear end thereof reduced, as at 2, to provide a portion that will enter a pen holder 3. The forward end of the body tapers to provide a writing point 4:, which is split, as at 5. The body 1 is provided with a centrally depressed portion 6, having a chamber 7 for writing fluid.

Arranged upon the body 1 is a pen point shaped guard 8, having the longitudinal edges thereof soldered or otherwise connected, as at 9, to the body 1 adjacent to the longitudinal edges thereof. The central portion of the guard 28 is raised above the chamber 7, thereby providing a space 10 between the body 1 and said guard. The forward pointed end of the guard has a slit 11 similar to the body 1, and the rear end of the guard has a small notchl2 serving functionally as an air vent, whereby when the pen is in use, ink will readily flow from the chamber 7 In using the pen point, the pressure brought to bear upon the writing point 4 causes the split 5 to open, allowing the slitted end of the guard 8 to protrude into the slit of the body 1, thereby causing the ink within the chamber 7 to flow directly into the open slit of the pen point, and on to the paper which receives the writing.

It is thought that the utility of the pen point attachment will be apparent without further description, and while in the drawing there is a preferred embodiment illustrated, it is to be understood that such changes can be resorted to as fall within the scope of the appended claim.

What I claim is:

A pen point including a body, a shank and a tapering split writing end, said body portion having its upper face depressed to provide a fiuid chamber extending in close proximity to the shank, and a longitudinally-extending guard arranged upon and having its sides secured to the outer face of said body, said guard projecting rearw'ardly of said recess and having its intermediate portion extending across and spaced from said chamber, said guard having the forward portion tapering and split, said tapering portion of the guard normally spaced from and capable of entering said writing end when pressure is brought to bear upon the latter, said guard havlng its rear edge thereof notched to provide an air vent, said guard of a length less than said pen point.

In testimony whereof I aflix my signature in the presence of two witnesses.

FRANK BUMER.
